Find LCM of 792,780,811,205,520 with Prime Factorization
| 2 | 792, 780, 811, 205, 520 |
| 2 | 396, 390, 811, 205, 260 |
| 2 | 198, 195, 811, 205, 130 |
| 3 | 99, 195, 811, 205, 65 |
| 5 | 33, 65, 811, 205, 65 |
| 13 | 33, 13, 811, 41, 13 |
| 33, 1, 811, 41, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 13 x 33 x 1 x 811 x 41 x 1 = 1711761480
Therefore, the lowest common multiple of 792,780,811,205,520 is 1711761480.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
792 x 780 x 811 x 205 x 520 = 53406958176000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
811 : 1, 811
205 : 1, 5, 41, 205
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 792,780,811,205,520, is 1.
Now, the common factors can be found like this.
792:2x 2x 2x 3x 3x 11
780:2x 2x 3x 5x 13
811:811
205:5x 41
520:2x 2x 2x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 3x 5x 5x 13 = 31200
Therefore, the value for common factors is 31200.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 53406958176000/(1x31200)
LCM = 53406958176000/31200
LCM = 1711761480
Thus, we can understand that the LCM of 792,780,811,205,520 is 1711761480.
